Best ResponseYou've already chosen the best response.07.A musical tone sounded on a piano has a frequency of 261.6 Hz and a wavelength of 1.31 m. What is the speed of the sound wave? A. 646 m/s B. 34.3 m/s C. 243 m/s D. 343 m/s 8.Bats chirp at high frequencies that humans cannot hear. They use the echoes to detect small objects, such as insects, as small as one wavelength. If a bat emits a chirp at a frequency of 60.0 kHz and the speed of sound waves in air is 340 m/s, what is the size in millimeters of the smallest insect that the bat can detect?

Best ResponseYou've already chosen the best response.0Would 4 be B? And with seven and eight, I just need to know how to figure it out. This is literally my first class in physics since elementary school my school is crappy so I barely have the basics of physics.

Best ResponseYou've already chosen the best response.1Regarding 7th and 8th ... Actually there's a standard equation \[V = f \lambda\] V= Velocity f= Frequency and the other symbol stands for the wave length
